Struktura přirozené obnovy smrkových porostů s příměsí buku a jedle
Zahradník, Tomáš
The main objective of this study was to determine the status and parameters of natural regeneration of spruce forests with an adulterant of beech and fir trees on the property within the HS 531. One of the objectives was to make an inventory of natural forests regeneration, then in the selected stand groups to be analyzed depending on the structure of shelterwoods, exposure and ground slope. The last sub-objective on the basis of these results, it was to optimize the regeneration process those shelterwoods. During a field investigations was natural regeneration detection on a total area of 35.77 hectares, ie. 8.47% of the total area of forest groups in which natural regeneration occurs, and its potential is high. From the outputs of statistical analyzes showed that species composition of natural regeneration is affected by the shelterwoods composition of vegetation. At all investigated areas of the criterion of minimum numbers of individual trees per hectare (i min. MZD counts) by Department of Agriculture no. 139/2004 Coll. In terms of growth parameters should sloped terrain affect the height of the aboveground part on height increment of individual trees, Exposure was important only for height increment. Wildlife here has an impact on the shattering of natural regeneration (especially for fir, less then in beech) and without any special protective measures will be very complicated to work with it and secure it biologically. Optimize forest regeneration procedures based on the results of the analysis depending on the structure of ashelterwoods, unfortunately, can not be conclusively recommended
